The royal couple is using their celebration of love to highlight the causes close to their hearts.

For a royal couple, having a wedding registry is so 2017, if not downright medieval. That's why for Prince Harry and Meghan Markle's wedding, they're requesting their guests and well-wishers make charitable donations in lieu of wedding gifts. While not every engaged couple can afford to be as altruistic, this is one wedding trend we hope catches on in 2018 and beyond.

According to a press release from Kensington Palace on April 9, "Prince Harry and Ms. Meghan Markle are incredibly grateful for the goodwill shown to them since the announcement of their engagement and are keen that as many people as possible benefit from this generosity of spirit. The couple have therefore asked that anyone who might wish to mark the occasion considers making a donation to charity, rather than sending a wedding gift."

The release also stated that the engaged couple "personally selected" seven organizations "which represent a range of issues that they are passionate about," including the Children's HIV Association (CHIVA), Crisis, the Myna Mahila Foundation, Scotty's Little Soldiers, StreetGames, Surfers Against Sewage and The Wilderness Foundation UK. All these organizations reflect their "shared values" of empowering women, conserving the environment, ending homelessness, helping people with HIV, and supporting the Armed Forces, though neither the prince nor princess-to-be "have any formal relationships with the charities chosen."

Not to be outdone, Prince Harry is also noted for his support of environmental and conservation efforts, as well as his military background. So it's probably safe to say he was the one to suggest putting Scotty's Little Soldiers, which supports children who have lost a parent serving in the British Armed Forces, on the couple's charity list.

Prince Harry is also following in his mother, Princess Diana's, humanitarian footsteps with the inclusion of Crisis, a national charity supporting people who are homeless, and CHIVA, which benefits children and their families living with HIV, on the wedding's charity registry. Diana's longtime support of both organizations most likely inspired her youngest son to take up the cause in the years since her passing.
